Optoma is one of the better rated projector manufacturers according to average reviews from experts and users, and Optoma also has good reviews for its 20000:1 contrast ratio data projectors.
Supports Full HD
The Optoma DS347 supports full HD. Most of the other 20000:1 contrast ratio data projectors that were released around the same time as the DS347 also support full HD.
We think you might also be interested in other multimedia projectors which also support full HD including the Optoma DS348 (£175.00), or the Acer X115H (£249.99).
The Optoma DS347 supports 3D, as do most of the other latest 20000:1 contrast ratio data projectors.
Quite Long Service Life of Lamp (economic Mode)
With a service life of lamp (economic mode) of 8,000 hours, the Optoma DS347 has one of the longer service life of lamp (economic mode)s amongst 20000:1 contrast ratio data projectors of this age. The average service life of lamp (economic mode) of similar spec projectors that were launched in the last 12 months is 6,600h, and the service life of lamp (economic mode)s range from 1,000h to 24,000h.
Fairly Big Offset
The offsets of projectors that are a comparable age to the DS347 range from 30% to 120%, and the average offset is 90%. At 115 percent, the Optoma DS347 has a quite big offset compared to most of the other newly released 20000:1 contrast ratio data projectors.
Quite Quiet Noise Level
At only 29 decibels, the Optoma DS347 has a quite quiet noise level compared to most of the other 20000:1 contrast ratio data projectors that have been available for the last year. The average noise level of comparable spec multimedia projectors that are a similar age to the DS347 is 31dB, and the noise levels range from 22dB to 35dB.
It may also be worth also looking at one of the alternative 29dB noise level projectors currently available including the Optoma EH341 (£663.30) which has better reviews.
If you would consider a data projector with a louder noise level then you might want to look at the W331 (£467.67) (29dB), or the DS348 (£175.00) (29dB) both from Optoma.
+3 More reasons for
The weights of projectors that have been around for the last year range from 110g to 40kg. At only 2.2 kilograms, the Optoma DS347 is quite light compared to most of the other projectors that have been around for around the same time as the DS347.
Very Low Power Consumption (economy Mode)
At only 187 Watts, the Optoma DS347 has a quite low power consumption (economy mode) compared to most of the other new projectors. The lowest power consumption (economy mode) of recently released data projectors is 170W, the highest is 370W, and the average power consumption (economy mode) is 220W.
7 Reasons Against
Does Not Have a Built-In Speaker(s)
The Optoma DS347 does not have a built-in speaker(s), unlike most of the other 20000:1 contrast ratio data projectors that were launched in the last year which have a built-in speaker(s).
Does Not Support Wi-Fi
The Optoma DS347 does not support wi-Fi, although it is worth keeping in mind that most of the other recently released comparable spec multimedia projectors also do not support wi-Fi.
Only SVGA (800x600) Projector Native Resolution
The highest resolution of the Optoma DS347 is SVGA (800x600). That's 53% less resolution than the most common projector native resolution of WXGA (1280x800).
This data projector's resolution (SVGA (800x600)) is in fact the worst resolution amongst all similar spec multimedia projectors that were launched around the same time as the DS347.
A WUXGA (1920x1200) projector native resolution is the best resolution across similar types of data projector.
Only 800 X 600 (SVGA) Supported Graphics Resolutions
The Optoma DS347 supports a maximum resolution of 800 x 600 (SVGA). That's 79% less resolution than a 1920 x 1200 (WUXGA) projector, which is the most common resolution supported by multimedia projectors that are a comparable age to the DS347. The resolution of all 20000:1 contrast ratio data projectors that are a comparable age to the DS347 ranges from 640 x 480 (VGA) (worst) to 1920 x 1200 (WUXGA) (best).
+4 More reasons against
Quite Dim Projector Brightness
At only 3,000 ANSI lumens, the Optoma DS347 has a quite dim projector brightness compared to most of the other latest 20000:1 contrast ratio data projectors. The projector brightnesss of projectors that are a comparable age to the DS347 range from 300 ANSI lumens to 5,400 ANSI lumens, and the average projector brightness is 3,400 ANSI lumens.
If this data projector projector brightness is too dim for you then you might also want to look at the P1285 TCO (£424.22) (3,200 ANSI lumens), or the A1300W (£516.20) (3,200 ANSI lumens) both from Acer or the Optoma GT760A (£404.28) (3,200 ANSI lumens).
Very Small Uniformity
The Optoma DS347 has one of the smaller uniformitys (only 75 percent) amongst similar spec data projectors of this age. Across all the comparable spec multimedia projectors that have been on the market for a similar time to the DS347 the uniformitys range from 70% to 90%.
Quite Small Matrix Size
The Optoma DS347 has one of the smaller matrix sizes (only 0.55 inches) amongst 20000:1 contrast ratio data projectors of this age. Across all the projectors that were launched in the last 12 months the matrix sizes range from 0.45" to 0.67", and the average matrix size is 0.62".

Total running cost over 5 years
Running costs for this projector have been estimated based on other similar projectors. If you know how much electricity and water the Optoma DS347uses then please let us know by entering those figures in the boxes above.
Running this projector over 5 years will generate 0.38 tonnes of carbon dioxide (CO2).
To offset that much CO2 you would need to plant 10 tree seedlings and grow them for 10 years.
